Acquisition Modules and Platinum Firmware Receiving Data
10 Receiving Data
The modular architecture of Platinum software allows seismic data to be
received simultaneously from a number of sources and using a number of
protocols. Extra protocols can be implemented by request: please contact
Güralp Systems Ltd for more details.
At the time of writing, Platinum firmware is shipped with support for CD1.1,
Güralp Compressed Format (GCF) data received over serial ports, GCF data
received over a network using the Block Recovery Protocol (BRP) and GCF
data forwarded from a copy of Scream or a Scream server, such as a
CMG-EAM.
The use of CD1.1 is covered in a separate manual, MAN-EAM-1100. The use
of the other receivers is described in this section.
10.1 GCF from serial devices
Any or all of the serial ports may be configured to receive GCF data from a
serially attached digitiser or digital instrument.
To configure a port for this purpose from the web interface, select:
Configuration → Serial ports
or
Configuration → All options → Serial ports
The following screen is displayed:
To configure a GCF input port from the command line, start gconfig and
select “Serial ports” from the top level menu.
Each port on the system is listed along with its function and line speed. Any
port can be used for any function with the exception of the console port,
which is dedicated to the terminal function, and the internal ports used for
inter-module communications in CMG-DAS units.
Select the link for the serial port you wish to configure for GCF input.
